摘要

瓦马纳普拉姆河流域（VRB）的植物种类繁多，包括来自 50 个植物科的 152 个不同物种。其中以菊科（Poaceae）、豆科（Leguminosae）、天南星科（Araceae）和天南星科（Aseraceae）植物最多，共有 13 种。大戟科（Euphorbiaceae）、刺桐科（Acanthaceae）、芹菜科（Apocynaceae）和茜草科（Rubiaceae）也是生物多样性热点地区。VRB 的植被特征是植物形态和生态位的动态相互作用，有 74 种草本植物、30 种灌木、12 种禾本科植物、1 种藤本植物和 35 种参天大树。由于水文因素的影响，草本植物在这一环境中生长茂盛。采样点 P6 和 P5 显示出较高的相对频率和密度，主要物种有 Macaranga peltata、Ficus hispida 和 Swietenia macrophylla。香农-维纳多样性指数（Shannon-Wiener diversity index）等多样性指数再次证实了 VRB 的热带森林特征。Beta 多样性模式揭示了不同村委会之间独特的植物物种分布动态，强调了其生态复杂性。这项研究强调，在这个环境活跃的地区，需要专门的管理和保护技术。

Assessing Riparian Floristic Diversity and Vegetation Dynamics in the Vamanapuram River Basin, Kerala: A Comprehensive Analysis

The Vamanapuram River Basin (VRB) is home to a diverse range of plant species, including 152 distinct species from 50 botanical families. Poaceae, Leguminosae, Araceae, and Aseraceae are the most abundant, with 13 species. Euphorbiaceae, Acanthaceae, Apocynaceae, and Rubiaceae also contribute to the biodiversity hotspots. The VRB’s vegetation profile is characterized by a dynamic interplay of plant forms and ecological niches, with 74 herbs, 30 shrubs, 12 grasses, 1 liana, and 35 towering trees. The Poaceae family thrives in this environment due to hydrological factors. The sampling sites P6 and P5 exhibit high relative frequency and density, with key species like Macaranga peltata, Ficus hispida, and Swietenia macrophylla. Diversity indices like the Shannon-Wiener diversity index reaffirm the VRB’s tropical forest character. Beta-diversity patterns reveal unique plant species distribution dynamics among different panchayaths, emphasizing their ecological complexities. The study emphasizes the demand for specialized management and conservation techniques in this environmentally active region.

期刊介绍： The journal was established initially by the name of Journal of Environment and Pollution in 1994, whose name was later changed to Nature Environment and Pollution Technology in the year 2002. It has now become an open access online journal from the year 2017 with ISSN: 2395-3454 (Online). The journal was established especially to promote the cause for environment and to cater the need for rapid dissemination of the vast scientific and technological data generated in this field. It is a part of many reputed international indexing and abstracting agencies. The Journal has evoked a highly encouraging response among the researchers, scientists and technocrats. It has a reputed International Editorial Board and publishes peer reviewed papers. The Journal has also been approved by UGC (India). The journal publishes both original research and review papers. The ideology and scope of the Journal includes the following. -Monitoring, control and management of air, water, soil and noise pollution -Solid waste management -Industrial hygiene and occupational health -Biomedical aspects of pollution -Toxicological studies -Radioactive pollution and radiation effects -Wastewater treatment and recycling etc. -Environmental modelling -Biodiversity and conservation -Dynamics and behaviour of chemicals in environment -Natural resources, wildlife, forests and wetlands etc. -Environmental laws and legal aspects -Environmental economics -Any other topic related to environment
